Mycosis vaginalis is contagious, either directly or indirectly. The most common direct transmission is through sexual intercourse, and indirect transmission can be through bath towels, underwear, underwear, toilets and other objects. In general, the mucosal surface of the skin is infected with mold, not necessarily will suffer from mycosis, because mold is a conditional pathogenic bacteria, when the conditions are met, the disease will occur. Under normal circumstances, a certain number of mycobacteria can live in the vagina, but they do not develop. When the immunity of the body is reduced or the pH of the vagina changes, which is more suitable for the growth of mycobacteria, they will multiply and cause vaginal inflammation. If you don’t take safe and effective protection measures during sex, you may infect men, but it usually doesn’t develop, and it will be transmitted to women through sex again, so mycosis vaginitis is easy to be prolonged.
